Published reference ranges
Published values for T3, free vary along one axis:
- age
Because a single unstratified figure would misrepresent them, none is shown here.
Published values vary by sex, age, time of collection, menstrual cycle phase and analytical method. The interval applicable to a patient's result appears on that patient's report.
